             Summary: SQLContext.getConf(key, null) should return null, but it throws NPE
                 Key: SPARK-21588
                 URL: https://issues.apache.org/jira/browse/SPARK-21588
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Burak Yavuz
            Priority: Minor


SQLContext.get(key) for a key that is not defined in the conf, and doesn't have a default value defined, throws a NoSuchElementException. In order to avoid that, I used a null as the default value, which threw a NPE instead. If it is null, it shouldn't try to parse the default value in `getConfString`
